INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.
lBefore starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer toMA-14, "
RECOMMENDED FLUIDS AND LUBRICANTS".
lUse procedure below to check for fuel leakage.
–Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
–Start engine. With engine speed increased, check again for fuel leakage at connection points.
lRun engine to check for unusual noise and vibration.
lWarm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids
including engine oil and engine coolant.
lBleed air from lines and hoses of applicable lines, such as in cooling system.
lAfter cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
Summary of the inspection items:
*1: Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.
*2: Check engine oil level 10 minutes after engine stopped.
